dt-bindings: phy: imx8mq-usb: fix fsl,phy-tx-vboost-level-microvolt property
commit 5b3a91b207c00a8d27f75ce8aaa9860844da72c8 upstream.
The ticket TKT0676370 shows the description of TX_VBOOST_LVL is wrong in
register PHY_CTRL3 bit[31:29].
011: Corresponds to a launch amplitude of 1.12 V.
010: Corresponds to a launch amplitude of 1.04 V.
000: Corresponds to a launch amplitude of 0.88 V.
After updated:
011: Corresponds to a launch amplitude of 0.844 V.
100: Corresponds to a launch amplitude of 1.008 V.
101: Corresponds to a launch amplitude of 1.156 V.
This will correct it accordingly.
